To all whom it may concern-.-

Be it known that I, EGBERT G. HOPKINS, a citizen of the United States, residing in the city of Rockford, in the county of Winnebago and State of Illinois, have invented new and drawings, in which Figure 1 is an isonietrical representation of a stove embodying my invention, in which a portion of the gas or smoke escape pipe is broken away to more clearly show the construction. Fig. 2 is also an isometrical representation of my improved stove, in which the upper plate or top of the stove is omitted. Fig. 3 is an'elevationof one of the vapor-burners, showing its position relatively with the stove; and Fig. 4 is an isometrioal representa tion of a grated covercapable-of use instead of the griddle-plates.

I In the figures, A represents end standards, of open frame-work, connected toward their lower ends by means of horizontal rods a, on which is supported a drip-shelf, B. These end standards and their connections constitute the supporting-frame of thestove.

The bottom plate of my improved stove con sists of the plateportion 0, provided with openings b, of a proper size to receive the burners. These openings are provided with a depending ring portion, 0, which serves to protect the flame of the burner supportedtherein from disturbing side air-currents, and cause the heat generated by the burnersto ascend into the stove. The outer edge portion of this bottom plate is provided with an uprising rim D, of suitable height. cal rim, on its front side, is provided with windows cl, placed opposite the burners, through which the. burners can be seen without removing the articles placed over the burners.

;plate. tions, 1 and n, by a vertical wall, m, on the same radial line with the check-valve or damper, with'the outer. end of which it connects, i and is employed 'to separate the rear cham- This verti-' At 0 is'represented a center, rectangular in plan, rising from the center of the bottom plate to the same height of the uprising rim on the outer edge of the plate.

- At his represented a vertical wall, radiating from the front side of the rectangular. center, rising from the bottom plate to the height of the rectangular center and outer rim, with which it connects, dividing the front half of the stove centrally between the burners into equal sections, E and F. The remaining three sides'of the rectangular center 6 are each provided with a radial slot, '5, to receive the jour nal end of a checlovalve or damper, to oscillate therein freely. In the same radial line with the radial slots 13 the outer rim, D,-is provided with vertical slots k, or otherwise fitted to receive the'journal-bearing of a check-valve or damper, to' oscillate therein.

At H are represented check-valves or dampers of blade form, having their ends produced I in journal form, fitted to enter and oscillate in the bearings in the rectangular center and in the outer uprising rim, and serve as divis ion-walls to the four equal divisions, E, F, I, and K.

At L is represented a stove-pipe support, projecting from the rear center of the bottom This support is divided into two secbers, I and K.

At M'is represented the top or upper plate of the stove, provided in the usual manner with openings .N, fitted in the usual manner with removable griddle-plates I and is fixed in place on the stove by means of suitable screw-bolts in its several corners. This tip a stove-pipe. This collar is of proper dimensions to engage the stovepipe support, on

which it rests This collar is provided with- 'a section of a stove per plate is fitted with a collar, 0, to receive ICO its connection with the collar. This pipe is designed to connect with a suitable fine, or extend to communicate with the external air.

At 1? is represented a supply-pipe having its lower end portion placed under the front portion of the stove, slightly rearward of a vertical plane passing through the centers of the openings bin the bottom plate. This portion of the supplypipe is supported in an adjustable manner by means of slotted bearings 11, havingan adjustable connection with the slotted bars P of the supporting-frame, on which the slotted bearings are made laterally and vertically adjustable, and held in their adjusted position by means of clam ping-screws passing through the slotted parts. From this connection of the supply-pipe with the frame it extends rearward on one end of the stove, and rises through a loop-support, p, and having its upper end provided with a fluid-reservoir, R. From the horizontal portion of the supply-pipe, at proper intervals, rise branch pipes 12", which connect with other branch pipes, p, on which the burners are supported in the vertical center of the openings 1) in the bottom plate. The burners employed in this instance are of one of the known forms, consisting of a perforated dome, 8, having a depending tube, t. A vertical valve-tube, 8, provided with a cup, .9, to contain fluid to heat the burner, is centrally connected with the branch pipe 12, which is provided with a needle-valve, 8', having a serew-thread connection with the axial center ofthc valve-tube, to engage the valve-seat in the upper end of the tube centrally under the depending tube t of the dome.

At T is represented an open grate, designed to be employed instead of the removable griddle-plates when required.

In the use of my improved stove the fluid is admitted to the cup and to the burner in the usual way, and ,whenignited, the valve or damper in rear of the burner and in the stovepipe in the same chamber are opened, which will carry off all the smoke. Vhen the burner has become sufficiently heated to generate gas properly, the dampers may be closed, and the heat produced utilized in heatingthe contents of the vessels placed in or over the opening over the burner. hen such vessel is suiiiciently heated, it may be placed 011 the opening in rear of the burner, and another vessel put in its place over the burner. The valve in rear of the burner is then opened, and the heat will extend to the rear chamber, to keep the contents of the vessel in the rear chamber hot. After the contents of the second vessel The valve between the two rear openings is then opened, which will permit the heat from the burner to keep the contents of the second vessel hot while the third vessel is heating. 6 In the use of my improved stove in the man ner described, it will be necessary to properly adjust the valves in the stove-pipe collar to insure sufficient draft to properly support combustion and conduct the heated current to the chamber required, all of which will be readily suggested. It will also be seen that when the two burners are ignited, and the several dampers separating the chambers of the stove are opened, that vessels placed upon 7 all the openings will be exposed to the heat generated by the burners.

From the foregoing it will be seen that in the use of my improved stove I am enabled to produce greater results from the consumption ofa given amount of liquid fuel than can be produced in an open single-plate stove as ordinarily constructed. In the foregoing Ihavc represented my improved stove with but two burners and four openings; but, evidently, this 8 system may be reduced to a single burner, or it may be increased to any required extent by which its capacity maybe increased to meet the requirements of large establishments.

I claim as my invention- 0 The con'ibination, in a vapor-stove fitted with dampers or valves capable of use to separate the openings into separate and independent chambers, ofa top plate provided with a pipe-collar fitted with valves or dampers eommunicating with the independent burnerchambers, substantially as set forth.

4. The combination, with the supply-pipe and with the supporting-finme, of adjustable bearings supporting said supply-pipe on the supportirig-frame, and made adjustable therc- 1 15 on, substantially as and for the purpose set forth.
